For the given pair of equations, give the slopes of the lines, and then determine whether the two lines are parallel, perpendicu

Nat2105 [25]

Answer/Step-by-step explanation:

Given,

10x - 3y = 3

3x + 10y = 30

Rewrite both equation in slope-intercept form, y = mx + b.

Where, m = slope of the line.

Thus,

✔️10x - 3y = 3

-3y = -10x + 3

y = 10/3x - 1

Slope of this line would be 10/3

✔️3x + 10y = 30

10y = -3x + 30

y = -3/10x + 3

The slope of this line is -³/10.

✔️The two lines are pendivukar to each other because the slope of one is the negative reciprocal of the other.

Answer:

11. AW║BY

12. DX║YZ

13. AW║YZ

14. AW║DZ

Step-by-step explanation:

11. If alternate interior angles are congruent, the lines the transversal crosses are parallel.

12. The sum ∠5+∠6 is an alternate interior angle with ∠10. The reasoning of problem 11 applies.

13. If same-side interior angles are suppplementary, the lines the transversal crosses are parallel.

14. Lines perpendicular to the same line are parallel.

A paperweight is shaped like a triangular pyramid. The base is an equilateral triangle. Find the surface area of the paperweight

stich3 [128]

Answer:

The surface area of the paperweight is $SA=8.3\ in^2$

Step-by-step explanation:

we know that

The surface area of the triangular prism is equal to the area of its triangular base plus the area of its three triangular lateral faces

<em>Find the area of its triangular base</em>

$SA=\frac{1}{2}(2)(1.7)$

$SA=1.7\ in^2$

<em>Find the area of its three triangular lateral faces</em>

$SA=3[\frac{1}{2}(2)(2.2)]$

$SA=6.6\ in^2$

Adds the areas

$SA=1.7+6.6$

$SA=8.3\ in^2$
